Model XTSLIN-20X-B1 features approximately 50W of saturated output
power, 25W of linear power using MIL-STD-188-164 definition at mid-band,
and more than 20W of linear power across the 500 MHz frequency band (7.9
- 8.4 GHz) over a temperature range of -40⁰C to +60⁰C. This high linear
output power level is achieved at less than 120W prime power consumption
across all conditions, and comes in a self-cooled feed-mount package
that can handle the toughest environments.

“With limited budgets and increasing bandwidth demands for both
commercial and military SATCOM systems, users are looking to benefit
from the available capacity that the X-band spectrum offers,” said John
Branscum, President of Comtech Xicom Technology, Inc. “This new BUC
enables system integrators to offer highly compact transportable and
man-portable SATCOM terminals that take advantage of Skynet, XTAR and
WGS to provide much higher data rates and more efficient operation. End
users no longer have to drop to kbps data rates in order to carry their
X-band terminal on their backs.”

The key to this unit’s compact size and light weight is its efficiency.
It operates as a Class AB amplifier with DC prime power draw ranging
from 108W at 20W linear RF power output, down to 60W at 2W linear power
output. Optional proprietary features offer even greater efficiency at
lower output power levels with Battery Saver mode to extend battery life
when conditions allow, making this the most flexible BUC of its kind for
manpack and transportable terminals.

The new X-band BUC accepts a 950-1450 MHz L-band input, upconverts it to
7.9 – 8.4 GHz X-band. The all solid-state unit uses GaN transistors to
amplify the signal to achieve full output power. Additional features
include temperature compensation, gain control, harmonic filtering,
tight gain variation and stability, a serial RS-232 digital monitor and
control interface, and options for operating with +24 or +48 VDC prime
power, provided over the IF line or through a separate connector.
